De-extinction and reintroduction efforts are reportedly underway for several species, including the dire wolf and others that have been extinct or considered lost. Some outlets suggest that certain animals, such as marmots and a previously extinct bird, have been successfully reintroduced or have reappeared, while others discuss the possibility of bringing back extinct animals like mammoths and dodos. However, the feasibility and implications of these efforts are being debated, with some experts expressing concerns about the concept of de-extinction.
